* The response only includes the signature. You must package it correctly before submitting the transaction to chain.
* Kadena does not have a deterministic serialized format. The exact serialized string used for signing must be submitted.

### Typescript Example with kadena.js <a href="#typescript-example" id="typescript-example"></a>

```typescript
import {
  Pact,
  readKeyset,
} from '@kadena/client'

const walletId = 'wa-6lbfv-9esgj-88s80c0qsih0a393'
const wallet = await dfnsClient.wallets.getWallet({ walletId })

const myAddress = wallet.address
const myPubKey = wallet.address.split(':')[1]
const toAddress = 'k:b7a3c12dc0c8c748ab07525b701122b88bd78f600c76342d27f25e5f92444cde'
const toPubKey = toAddress.split(':')[1]

// 1 KDA
const pactAmount = { decimal: '1.0' }

// coin contract
const contract = 'coin'

const transferCommand = Pact.builder
  .execution(
    (Pact.modules as any)[contract as 'coin']['transfer-create'](
      senderWallet.address, recipient, readKeyset('ks'), pactAmount)
     )
    .addSigner(myPubKey, (withCapability: any) => [
      withCapability('coin.GAS'),
      withCapability(`${contract as 'coin'}.TRANSFER`, myAddress, toAddress, pactAmount),
    ])
    // add public key of recipient here
    .addKeyset('ks', 'keys-all', toPubKey)
    // set the network Id for the transaction. For testnet use 'testnet04', for mainnet use 'mainnet01'
    .setNetworkId('testnet04')
    // here we set the chainId of the chain we want to broadcast to
    .setMeta({ chainId: '0', senderAccount: myAddress })
    .createTransaction()

const res = await dfnsClient.wallets.generateSignature({
  walletId,
  body: {
    kind: 'PactCommand',
    command: transferCommand.cmd,
  },
})
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs-legacy.dfns.co/d/api-docs/keys/generate-signature/kadena.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
